replacing engine oil filter every change

   / replacing engine oil filter every change #11  
I was a 3000 mile oil change guy for 30+ years. 20+ years ago I bought a Honda and the manual said 10K mile oil changes..... I think "No way", I ran the first one to 5K and did a used oil analysis - no wear metals and the oil was at less than half life... I tried a 10K oil change interval and sent out another used oil sample, very low wear metals and plenty of life left in the oil. I did a few more used oil samples at 10K intervals and they all came back fine. I've been a 10K mile oil change interval ever since.

I retired 8+ years ago and now only put 8K miles a year on each car, so they now get an annual oil change, along with the tractors and UTV.

A used oil analysis is money well spent.

I had a classmate of mine 60 years ago that said changing the oil but not the filter was like taking a bath while wearing your dirty socks.

Anyone else here besides me not trust oem recommended oil change at 10k intervals?
I'm sure I'll get some haters but I bought a Ford truck, no that's not it :rolleyes: this > From new I put full synthetic oil in it with a new filter every 10-15k miles. It idled excessively on job sites, hauled a lot of horses, and generally just got used hard for 160k miles. Friend bought it 8-10 yrs ago and the 04 F250 gasser is still doing ranch duty and pulling classic cars to shows. Miles unknown.

I got 2015 GMC Sierra 2500. Change oil and filter as it says in the manual: every 10k. Used regular oil till last year. Last year put synthetic by mistake...))

I've cut apart many filters and never seen even a speck of dirt or debris. But good quality auto oil filters are pretty cheap so I change them at the recommended intervals. Some of my OPE filter changes are 4 time longer than the OCI's.

I don't go by manufactures time intervals though. Ex: 7500 mile OCI's or 12 months. I'm not dumping 6 quarts of good M1 with 1500 miles on it just because of a calendar change. I've emailed both super majors and neither could give me a satisfactory reason other than to stay in warranty. But I make sure the oil gets good and hot to dry it out regularly.

Magnetic plugs do seem to pick up a little sludge over time.

Do you put on clean socks when you wash your feet?
